Backwater harm can be extremely costly - and therefore avoidance is quite affordable. For this reason make sure all areas beneath the backwater level with open drainage fittings are constantly protected by a backwater or non return valve. The backwater valve also referred to as a non return valve comes with free hanging vertical backwater flaps. These flaps make sure that a building's wastewater flows freely through the valve while simultaneously preventing any backwater from backing up into the building.

What is the Difference Between a Check Valve and a Non Return Valve?

A check valve is a certain type of valve which could prevent back flow from occurring. The check valve needs to be tested and meet very strict standards, which ensures fluids aren't able to be siphoned back into drinking water systems. Non return valves are similar in design to a check valve but are not able to meet the strict criteria of a check valve.
